Mechanical movement

ABSTRACT

This invention is a mechanical movement for converting reciprocating linear motion to rotary motion. An arm is pivotally connected at one end to a source of reciprocating motion. The opposite end of the arm is connected to a driving member mounted on a rotatable shaft at approximately a 45* angle to the longitudinal axis of the member. As the arm moves in response to the reciprocating motion, corresponding movement of the opposite end of the arm is effected, producing actuation of the driving member to rotate the shaft on which the driving member is mounted.

MECHANICAL MOVEMENT BACKGROUND AND OBJECTS OF THE INVENTION In parts ofthe United States and other countries where electrical power is notreadily available, it is common practice to employ windmills for raisingwater to the surface. In the operation of the windmill, there is areciprocating movement of the windmill lifting rod in response toactuation of the wind wheel by the wind. This reciprocating linearmotion of the windmill shaft constitutes a potential power source foroperating electrical generators, or other mechanical and electricalequipment.

It is therefore an object of this invention to provide a mechanicalmovement for converting reciprocating linear motion from a reciprocatingpower source to rotary motion of a shaft for driving mechanical orelectrical equipment.

Another object is to provide a mechanical movement of the characterdescribed wherein a rotatable driven member is positioned adjacent areciprocating linear power source, and a connecting assembly convertsthe linear motion of the power source to a rotary motion of the drivenmember.

A further object is to provide a mechanical movement including an armconnected at one end to a reciprocating shaft, the opposite end of thearm being joined to a cylindrical driving member which is mounted on arotatable shaft at an angle to the longitudinal axis of the cylindricalmember, the rotatable shaft being actuated by reciprocating linearmovement of the arm.

A still further object is to provide a mechanical movement of thecharacter described wherein the driving member is mounted on therotatable shaft at approximately a 45 angle to the longitudinal axis ofthe driving member, and said reciprocating and rotatable shafts are insubstantially parallel relationship to each other.

Other objects will be apparent from the following description of thepresently preferred form of this invention taken in conjunction with theappended drawings.

DESCRIPTION OF THE FIGURES OF THE DRAWINGS In FIG. 1, there isillustrated a reciprocating power source in the form of a shaft 20 suchas a windmill lifting rod which is adapted for reciprocating linearmotion upon actuation by a wind wheel. The mechanical movement assemblyof the present invention is generally designated 22 and is positionedadjacent shaft 20.

Assembly 22 includes a stationary frame member embodying a base 24 andend walls 26 and 28. As shown in FIGS. 1 and 5, standard bearing member30 and 32 are mounted in walls 26 and 28, which bearings are adapted toreceive a rotatable shaft 34.

As seen in FIG. 1, shaft 34 extends through and beyond end wall 28, asindicated at 36 to provide an extension member on which are suitablymounted drive pulleys 38 and 40 which are spaced from wall 28 and eachother by spacers 42 and 44. A shaft end cap is indicated at 46. Drivebelts 48 and 50 are driven by pulleys 38 and 40, the drive beltsextending to an electric generator or other apparatus (not :shown) to bedriven in a well known manner.

The assembly of the present invention further includes a driving membergenerally designated 52 which serves to rotate shaft 34 and is mountedthereon. As shown in FIGS. 6 and 8, driving member 52 includes a solidcylindrical body 54 at one end of which is peripherally mounted aconventional ball and race assembly 56. A bore 58 extends angularlythrough the central portion of member 54 at approximately a 45 angle tothe longitudinal axis of the member. As shown in FIG. 6, the boreextends from an end wall of the cylindrical member at the peripherallimit thereof, and extends through a diametrically opposite wallperiphery of the member at a point intermediate the length of thecylindrical body. Bore 58 is of substantially the same diameter as rod34 and is adapted for mounting thereon.

A collar 60 is fixed to the outer periphery of ball and race assembly56.As shown in FIG. 1, collar 60 is contiguous with assembly 56 throughthe major portion thereof, but a portion is spaced from the periphery ofthe bearing as indicated at 62. Spaced portion 62 is further providedwith an opening 64 through which an arm 66 extends into fixed engagementwith the outer periphery of assembly 56. A telescoping sleeve 68 engagesthe opposite terminal of arm 66, the sleeve being engaged with auniversal connection 70 fixed to reciprocating shaft 20 to permitswiveling engagement of arm 66 with respect to the shaft. Sleeve 68compensates for the difference in distances between driving member 52and reciprocating shaft 20 as the arm moves between its upper and lowerlimits.

OPERATION In use of the assembly of the present invention, actuationthereof is initiated by connection of arm 66 and sleeve 68 throughuniversal connection 70 to reciprocating shaft 20 which constitutes thepower source of the present invention. As the shaft 20 begins itsreciprocating linear motion, a corresponding reciprocating movement ofarm 66 occurs, as shown to advantage in FIG. 1. The movement of arm 66in turn creates a progressive movement of cylindrical member 56 byvirtue of the angular relationship of bore 58 to rotatable shaft 34 inwhich it is mounted. This progressive movement is illustrated in FIGS.2, 3 and 4. By virtue of the frictional engagement of that portion ofthe cylindrical member surrounding rotatable shaft 34 with the sur' facethereof, a corresponding rotation of the shaft occurs, the shaftrotating one-half a revolution for each movement of arm 66 from itsupper to its lower position and vice versa. A complete revolution of theshaft is effected by a complete cycle of the reciprocating shaft 20 fromits upper limit to its lower limit and back to its upper limit. Bearingassembly 56 permits relative rotary movement between the assembly andcylindrical member 54.

Continued reciprocating movement of shaft 20 produces a constantrotation of shaft 34 and this rotary motion is transmitted through ashaft extension 36 to pulleys 38 and 40 which are fixed thereto. Thiseffects a corresponding movement of belts 48 and 50 for transmitting therotary motion to a generator or other apparatus to be driven.

It is to be of course understood that the present invention is capableof adaptation for translating any reciprocating linear motion to'rotarymotion for directly driving any apparatus directly connected torotatable shaft 34 as well as using the shaft as a power take off fordriving the apparatus through a belt and pulley arrangement.

While there has been herein shown and described, the presently preferredform of the present invention, it should be understood that such hasbeen done for purposes of illustration only, and that various changesmay be made therein within the scope of the appended claims.
